One thing Joe Biden has mentioned was adding more seat to the Supreme Court. Why would he suggest this? How would it benefit the Court?
Originally in 1789, there were six total justices (one Chief Justice and five Associate Justices). Seat #6 was added in 1807. Seats #7 and #8 were added in 1837, but in 1865 seat #7 was abolished. In 1863, seat #9 was added and the 10th seat (the last seat) was added in 1869. Since none of us were alive to see any differences, we can only see what history tells us.
